He’s grooming your mom and now your mom is ‘grooming’/readying her entire family, so he can run away from his situation in his home country and start again. The question is this: why is he running away? He has a roof over his head, he’s an adult, his aunt is forcing him to study so he can get a decent job?
Sorry this is ridiculous, he just thinks he wants an easier life and sees your mom as a way to get it. If he gets into your home, he won’t be getting a job, he’ll be playing games all day and eating food and doing nothing. Because that’s what he wants, to be taken care of.
I’m all for giving people opportunities, but this guy has no plan, beyond living with your mom. Also, again, he’s not a ‘kid.’ He’s an adult, let him figure things out for himself, or else he’ll always look for the easiest solutions and be a major problem for your family. Yes, he’s scamming your mom. Show her alle these responses and tell her to grow up and protect her kids lika an adult should do.
I want the same advice, but for cat parents without kids.
